Abstract

Un ensemble détanchéité destiné à des composants de turbine en segments comprend une bande détanchéité et un élément de cordon résilient compressé contre la bande pour fournir un chargement positif contre les faces détanchéité du segment. La bande détanchéité et lélément de cordon résilient sont engagés dans des cavités se confrontant définies dans les faces dextrémité des segments adjacents. Lélément de cordon résilient est communément tenu par les deux segments dans un état compressé contre la bande détanchéité.
